There seems to be very little in the way of detailed Amazon reviews using Lifepo4 batteries to upgrade Mobility scooters so I decided to write an extensive review.
Purchased these paired Lifepo4 Golden Mate 20ah scooter batteries for a Pride Revo 2.0 mid-size mobility scooter. New Lifepo4 batteries arrived with 13.25 (26.5 in series) charge.
Initial charge with YZPOWER 29.4V 4A Power Adapter for Electric Bike Mobility Scooter 24V Lithium Battery Charger 3-Pin XLR Connector charger also purchased on Amazon brought batteries to 14.6V (29.2 in series) Full Charge.
Ran scooter test which passed with flying colors - discharged batteries about 35% (~ 7 amps).
On second charge with the YXPOWER charger, charger kicked out at 14.1 (28.2) volts due to unbalanced batteries in battery packs. I kept charger connected for an additional 6 hours which slowly brought batteries up to a voltage of 14.6 (29.2).
Let batteries rest overnight and plugged in charger which shut off after a few seconds with ending voltage again 14.6 (29.2) (Indicating that batteries were now balanced and fully charged).
Re-Ran mobility scooter test and went one hour at full speed (~ 5 miles). Recharged batteries and based on recharge time estimated ~ 8 AH of capacity was used during the test which should give these batteries about a 10 mile range on this scooter (8AH * 2 hours = 16AH with 10%-20% of charge in reserve - YMMV).
Will update if any longevity problems arise, but from initial impressions these are great batteries for replacement / upgrade Lifepo4 scooter batteries.
Update: A few words on why I went with the GoldenMate brand over more expensive or popular brands - I reviewed dozens of videos of small battery teardowns on yo*tube. If you search yo*tube video for "Goldenmate 20ah" you will find a teardown video that shows the internal construction of the battery which is far better than most of the other batteries that I saw. Some of the differences:
- All battery cells sequestered from touching each other via cell holders - important for scooter batteries that are subject to a great deal of vibration and movement.
- Balance lead wiring also taped down and isolated.
- Low temperature protection tested.
As always, read my reviews with confidence - I do not take bribes / free products in exchange for writing good reviews.
